Objective: This study aims to evaluate the effect of two different pretreatment protocols-enamel deproteinization and bonding agent application-on the one-year survival of fissure sealants applied to permanent first molars in children. Background: Dental caries is a preventable yet highly prevalent multifactorial disease. Deep pits and fissures are particularly susceptible to caries development, especially in newly erupted molars. Although fissure sealants are considered one of the most effective preventive methods, their clinical success is largely dependent on long-term retention. Contamination of etched enamel surfaces with saliva or gingival fluid is a primary cause of sealant failure. To improve sealant adhesion, several pretreatment methods have been suggested, including bonding agents and enamel deproteinization. Methods: This randomized, controlled, double-blind clinical trial with a split-mouth design was conducted on healthy children aged 7-14 years. Each child contributed at least three permanent first molars to the study, randomly assigned to one of three groups: Group A - Acid etching + sealant; Group B - Acid etching + deproteinization + sealant; Group C - Acid etching + bonding agent + sealant. Clinical evaluations were performed at 3, 6, and 12 months using visual and tactile methods. Sealant retention, caries incidence, and marginal discoloration were recorded based on standardized criteria. Results \& Conclusion: This study seeks to clarify whether bonding agent or deproteinization pretreatment significantly improves sealant retention and reduces caries incidence compared to the conventional approach. Findings may contribute to defining the most effective clinical protocol for fissure sealant application, ultimately enhancing caries prevention and long-term treatment success in pediatric dental care.

the current study aims to assess virtual reality as an effective pain management technique for children undergoing different dental procedures. The iWear is the immersive virtual reality device was used for this study from (Vuzix®, Rochester, New York, USA). The iWear consists of a lightweight high-end pair of video headphones that contain pair of VR goggles

The purpose of this implementation science study is to determine whether Deliberative Loops are effective in increasing providers' adherence to the non-cavitated caries component of the American Dental Association's pit-and-fissure sealant evidence-based clinical practice guideline. The investigators use a stepped wedge design to randomly assign dental clinics to the Deliberative Loop intervention. In a Deliberative Loop, stakeholders receive background information, participate in a facilitated discussion, and share their views with leadership. The Deliberative Loop intervention is designed to help stakeholders form informed opinions; in this study, stakeholders will be forming informed opinions about the implementation interventions they think will increase their clinic's adherence to the guideline. The investigators hypothesize that compared with the pre-intervention period, following the intervention, providers will place or treatment plan sealants for significantly more occlusal non-cavitated carious lesions.
NCT05475145
BACKGROUND A simple method for arresting dentin caries with a tight seal of the cavity would exclude the need for injection and excavation, reduce the risk for dental fear and possibly postpone or eliminate the need for further treatment. AIM The aim is to evaluate success-rate and children's subjective experience of resin-based sealing (RBS) and resin-modified glass ionomer cement (GIC) for treatment of occlusal dentin caries in primary molars. DESIGN Children aged 2-9 years will be recruited to undergo RBS- or GIC-treatment treatment for occlusal dentin caries in primary molars. A parent will answer the Short Form of Children's Fear Survey (CFSS-DS; parental version). No excavation but etching with 38% phosphoric acid will precede RBS. Topical and local anaesthesia and excavation with high speed bur will precede GIC. Time for treatment will be estimated. The children will rank their experience of each treatment on a 7-grade face scale. The dentist will evaluate the child's experience, cooperation and the overall experience of the treatment on a four-grade scale. The treatment will be evaluated as "without remark" or "defective" after 3, 6, 12, 24 and 36 months. For statistical analysis the Chi-2-test, Wilcoxon-Signed-Rank-test and Paired t-test will be used.

Despite numerous techniques for enamel protection, occlusal caries still remains a problem. Sealing pits and fissures is considered to be an effective way of preventing caries development. Glass-ionomer cements are mainly recommended for pits and fissures sealing for two reasons. First, they are less susceptible to moisture which allows their use in noncooperable children or in partially erupted teeth where isolation could be a problem, and secondly, due to their potential to act as a fluoride reservoir making enamel more resistant to demineralisation. The purpose of the study is to clinically examine the caries-preventive effect of a glass-ionomer material for fissure protection in newly erupted permanent molars in children with low, moderate, and high caries-risk.
NCT02998814
The purpose of this study was to evaluate the retention rates of a fissure sealant placed using different adhesive protocols over 24 months.Twenty-four subjects with no restoration and caries received fissure sealants (Clinpro™Sealant, 3M/ESPE) placed with different adhesive protocols. A total of 292 sealants (73 for each group) were placed. The sealants were placed as follows; a-without adhesive (acid-etch only), b-with an etch-and-rinse adhesive (SingleBondTM), c-with a self-etch adhesive (AdperTMEasyBond), d-with acid-etch+self-etch adhesive (AdperTMEasyBond) by two previously calibrated dentists using a table of random numbers. Two other calibrated examiners, independently evaluated the sealants at baseline and at 6-, 12-, 18-, and 24-month recalls. Each sealant was evaluated in terms of caries formation being present or absent and retention using the following criteria: 1=completely retained, 2=partial loss, and 3=total loss. The Pearson χ2 test was used to evaluate differences in retention rates among the sealants for each evaluation period.
